Fin Plate

SFB+

With the SFB+ program, fin plate connections in steel construction can be designed. SFB+ performs all required verifications for fin plate connections in the configurations “secondary beam to steel beam” or “secondary beam to steel column”.

Material

The material can be selected differently for the main beam, secondary beam, support and fin plate.

  • Structural steel: S235, S275, S355, S450
  • Annealed steel (S275N – S460N)
  • Thermo-steel (S275M – S460M)
  • Weathering steel (S235W – S355W)
  • High-temperature steel (S460Q – S460QL1)
  • Hollow section, hot-finished (S235H – S355H)
  • Hollow section, hot-finished, fine-grain (S275NH – S460NH)
  • User-defined steel
Structural system

Available systems:

  • Fin plate connection: secondary beam to steel beam
  • Fin plate connection: secondary beam to steel column
  • Flexurally rigid connection at weld seam or at bolt centre of gravity
  • For a connection to a beam, the secondary beam can have a notch on top, on bottom, or on both sides

Cross-sections:

  • I-sections as standard shapes
  • User-defined I-sections
Loads
  • Depending on the selected design model (flexurally rigid at the weld seam or in the bolt pattern), design internal forces caused by axial force, moment, and shear force can be defined.
  • Design internal forces refer to the centre of gravity of the bolt pattern.
  • Multiple combinations of design internal forces can be entered.
Fasteners
  • Bolts (black bolts and fit bolts)
  • Sizes: M12; M16; M20; M22; M24; M27; M30; M36
  • Strength classes: 4.6; 5.6; 8.8; 10.9
Design

Either the elastic or plastic cross-sectional resistance of the fin plate is verified. For the verification of the weld seam, the user can select whether the simplified or directional method should be used. For the bolted connection, the verification of the embedding pressure as well as the verification of shear action are performed.

Thank you for your enquiry!

The merger of FRILO Software GmbH and DC-Software GmbH with ALLPLAN, completed and announced on 1 July, is leading to an increased volume of telephone and e-mail inquiries. In addition, necessary maintenance work in our CRM and ERP systems is causing temporary irregularities and delays in our operating processes. We, therefore, ask you to forgive us for the longer waiting times. We will endeavor to process your request as quickly as possible.

Thank you for your understanding.
